1. A positive correlation (r = 0.52) is found between hours spent playing with other children at age two and sociability in kindergarten. Answer the following questions based on this result. a. What does a positive correlation mean in this specific scenario? b. If someone concludes that requiring children to play with others at age 2 will increase sociability, what TWO common errors of interpreting correlations are being made? c. Calculate the coefficient of determination for this scenario. d. If...

If the p-value for a hypothesis test is 0.07 and the allowed probability of making a Type I error is 0.05, then the correct decision is to O reject the null hypothesis only if it is a one-tailed test. O not reject the null hypothesis. O reject the null hypothesis. O not reject the null hypothesis only if it a two-tailed test.

Suppose you want to determine whether there is a significant difference in mean test scores for females and males. The test is out of 600 points. Using the following hypotheses: Ho: U1 - U2 = 0 HA: U1 - U2 (not equal) 0 And alpha of 0.05 you obtain the following results t-test Two-sample assuming unequal variances Females Males Mean 525 487 Variance 3530.8 2677.818182 Observations 16 12 Hypothesized Mean Difference 0 df 25 t stat 1.803753 P (T<=t) one...
